we need to ramp up the pressure to tax these companies and fund a UBI *now*. if we don't, by the time they've already eliminated these jobs it will be too late, and they'll hold all the cards.

...talk about that and discuss mitigation strategies.

With this team, we decided to re-evaluate frequently, to listen to our gut feeling and to not give up too soon. Next time I do something like this, I will also use those four questions.

Improvement is not always linear. Sometimes, it's not easy to find out whether you are on the downward-part of a J-curve or on a genuine downward trend. I wanted them to think and...

Unser Journalismus orientiert sich oft an dem was und wie in den USA berichtet wird. Das muss schleunigst aufhรถren. WaPo ist eh verloren, einzelne Journalist*innen unter Druck und wenn CNN jetzt an Paramount geht wird das รผble Konsequenzen haben. Wir mรผssen unabhรคngig werden. Auch journalistisch.

The political effects of X's feed algorithm

Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects.
Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

A new paper shows that less than 2 months of exposure to Twitterโ€™s algorithmic feed significantly shifts peopleโ€™s political views to the right.

Moving from chronological feed to the algorithmic feed also increases engagement.

This is one of the most concerning papers Iโ€™ve read in awhile.

Tried to graft some #apple #trees for the first time - "Golden Noble" on a seedling I grew for 2 years now. I know the cuts are not good, but it was the best I could do.

Let's hope they grow - for future #bonsai or garden trees...

Did some quick winter pruning on some of my #bonsai (or, to be more precise, early-stage projects). But made no recordings, just a few quick cuts.

Maybe I'll shoot some new #videos in spring, when #repotting season starts.
